hash oil is a cannabis concentrate product composed of compressed or purified preparations of stalked resin glands, called trichomes, from the plant. It is defined by the 1961 UN Single Convention on Narcotic Drugs (Schedule I and IV) as “the separated resin, whether crude or purified, obtained from the cannabis plant”. The resin contains ingredients such as tetrahydrocannabinol (THC) and other cannabinoids—but often in higher concentrations than the unsifted or unprocessed cannabis flower.
Purities of confiscated hashish in Europe (2011) range between 4% and 15%. Between 2000 and 2005 the percentage of hashish in cannabis end product seizures was at 18%.
Hashish may be solid or resinous depending on both preparation and room temperature; pressed hash is usually solid, whereas water-purified hashish—often called “bubble melt hash”, or simply “bubble hash”—is often a paste-like substance with varying hardness and pliability; its color, most commonly light to dark brown, can vary from transparent to yellow, tan, black, or red. This all depends on the process and amount of leftover plant material (e.g. chlorophyll).
Hashish was the primary form of cannabis used in Europe in 2008. Herbal cannabis is more widely used in Northern America.

What is hashish (hash)?
- Hashish, often called hash, is a potent form of cannabis (marijuana) produced by collecting and compressing trichomes, the most potent material from cannabis plants. Marijuana is a green, brown or gray mixture of dried, shredded leaves, stems, seeds and flowers of the plant Cannabis sativa.
- Trichomes are the fine growths on cannabis plants that produce a brown or or orange sticky resin. The resin is high in THC.
- Hash is often dried and pressed into small blocks or made into an oil. It may also be added to food and eaten.
Hashish contains essentially the same active ingredients found in marijuana, except in a more concentrated THC form. Sinsemilla, hashish and hash oil are stronger forms of marijuana. These products are THC concentrates or extracts. They appear as a dark brown, waxy substance or can be made into an oil.
The active agent in hashish that leads to the “high”, like marijuana, is THC (delta-9-tetrahydrocannabinol).
As with marijuana, people who use hashish may experience a pleasant to intense euphoria, a sense of relaxation and a heightened sensory perception (such as brighter colors). Elevated mood, altered perception of time, and increased appetite may occur. Effects can also be unpleasant or cause paranoia or panic in novice users not experienced with concentrated levels of THC.
